Description

  The present invention relates to an apparatus for sandwiching a building material when a plate-shaped building material such as an outer wall material is lifted at a construction site or the like.

  Conventionally, when constructing an outer wall material such as a siding board at a construction site, an operator holds a heavy outer wall material one by one with both hands and carries it over a narrow scaffold to a construction site. Further, when the construction site is a high place, it has also been carried out that the worker underneath is manually lifted and handed over to the worker underneath. For this reason, the construction work of the outer wall material places a severe burden on the worker and also involves a risk of causing a fall accident. Therefore, conventionally, it has been necessary to improve workability and safety at the time of constructing such an outer wall material.

  In order to solve these problems, there are those disclosed in Patent Document 1 and Patent Document 2 below. That is, in Patent Document 1, a pair of sandwiching plates is provided in a link mechanism that intersects in an X-shape, a plate-like object is sandwiched by the sandwiching plates, and the plate can be lifted by a wire rope. A gripping device for the object is shown. Patent Document 2 discloses a lifting jig used for lifting a panel.

  Next, the best embodiment of the present invention will be described with reference to FIGS. In the sandwiching device for lifting a plate-like building material of this embodiment, a pair of support arms 1 and 1 formed by a horizontally long rod 2 and a support rod 3 and a horizontally long rod 2 and 2 of the support arms 1 and 1 are X-shaped. The support shaft 4 that connects the both support arms 1 and 1 so as to be openable and closable so as to intersect with each other, and the sandwiched suspension in which both ends are engaged with the positions of the front end sides of the horizontal eaves 2 and 2 of both support arms 1 and 1 The upper member 10, the open lifting member 15 whose both ends are engaged with the positions of the proximal ends of the horizontally long rods 2, 2 of both support arms 1, 1, and the support rod 3 of both support arms 1, 1 It is roughly constituted by a pair of sandwiching plates 20 and 20 pivotally attached so as to face the lower end.

  The support arm 1 is made of a flat metal plate, and is formed by a horizontally long rod 2 and a support rod 3 that hangs from the base end side of the horizontally long rod 2. Further, the support rod 3 includes horizontal flange portions 3a and 3a that are bent in the horizontal direction so that the base end side of the horizontally long rod 2 is separated in a bifurcated manner, and the other end sides of the horizontal flange portions 3a and 3a are directed downward. It is comprised from the bent vertical hook parts 3b and 3b, Furthermore, the fixing | fixed part 3c and 3c which bends inwardly at the lower end of the vertical hook parts 3b and 3b are formed. Further, a shaft hole for inserting a support shaft 4 to be described later is formed in a substantially intermediate portion in the longitudinal direction of the horizontally long rod 2, and the distal side of the horizontally elongated rod 2 (the base end side on which the support rod 3 is provided) In the upper part of the opposite side, a through hole for engaging a clamping lifting member 10 to be described later is formed, and further, an opening to be described later is provided on the side portion of the shaft hole of the horizontally long rod 2 on the support rod 3 side. A through hole for engaging the lifting member 15 is formed. In addition, a through hole for pivotally attaching a clamping plate 20 described later is formed on the distal end side of the fastening portions 3c, 3c of the support rod 3. In addition, the support arm 1 in this embodiment consists of two flat members, and is integrally fixed by welding the inner part of the horizontal eaves 2 to each other. However, it is not always necessary to form the support arm 1 by two members as in this embodiment, and it may of course be formed by one member. Moreover, although the support arm 1 in this embodiment showed the example formed by the flat metal plate, it does not necessarily need to be flat plate, and if the material can also maintain rigidity, it will be metal. It is not limited.

  Such a support arm 1 is a combination of two support arms 1 and 1 supported by a support shaft 4. That is, the pair of support arms 1 and 1 are formed by superimposing the horizontal elongates 2 and 2 in the direction in which the support eaves 3 and 3 are separated from each other, It is pivotally attached by inserting the spindle 4 which consists of. Therefore, the horizontal elongates 2 and 2 of the pair of support arms 1 and 1 are rotatable so as to intersect in an X shape with the support shaft 4 as a fulcrum. Thus, the support rods 3 and 3 are moved closer to and away from each other.

  The sandwiching and lifting member 10 is made of a flexible string, and ring members 11 and 11 having a through hole at the center are provided at both ends thereof. The ring members 11 and 11 of the sandwiching and lifting member 10 are fixed to the through holes formed at the upper ends of the laterally long rods 2 and 2 by the clasps 12. Further, a lifting wire rope 13 is connected to the sandwich lifting member 10. In addition, in this embodiment, although the example which fixed the both ends of the clamping lifting member 10 to the front end side upper part of the horizontal elongate rods 2 and 2 was shown, the position which fixes both ends of the clamping lifting member 10 Is not necessarily limited to this position, and the object of the present invention is to fix to the range from the support shaft 4 to the distal end side (opposite to the base end side on which the support rod 3 is provided) of the horizontally long rods 2 and 2. Can be achieved.

  The open lifting member 15 is also made of a flexible string, and ring members 16 and 16 having a through hole in the center are provided at both ends thereof. The ring members 16 and 16 of the open lifting member 15 are fixed to the through holes formed in the side portions of the horizontally long rods 2 and 2 on the side of the support rod 3 by the clasps 17. In this embodiment, the both ends of the open lifting member 15 are fixed to the side portions of the horizontally long rods 2 and 2 on the side of the support rod 3, but both ends of the open lifting member 15 are fixed. The position to be performed is not necessarily limited to this position, and the object of the present invention can be achieved if the horizontal elongated rods 2 and 2 are fixed in a range from the support shaft 4 to the support rod 3.

  The pair of sandwiching plates 20 and 20 is formed of a rectangular solid iron plate having a certain area. In addition, a plurality of flat head screws 21 are inserted into the back surfaces of the sandwich plates 20 and 20 so that the two stop plates 22 and 22 are fixed to each other at an appropriate interval. The bearing plates 23 and 23 are projected on the surface by welding. And the fixing parts 3c and 3c formed in the lower end of the support rods 3 and 3 of the said both supporting arms 1 and 1 are pivotally attached to the bearing plates 23 and 23 by the spindles 24 and 24 which consist of a volt | bolt and a nut. . Thereby, the lower end of the support rod 3 can be tilted in a vertical plane with respect to the sandwiching plates 20 and 20. Moreover, the opposing inner surfaces of both the sandwiching plates 20 and 20 are formed flat, and a pair of elastic pads 25 and 25 are adhered to the inner surfaces of the respective sandwiching plates 20 with an appropriate interval therebetween. Yes. Further, security string members 26, 26 are secured to the lower ends of the bearing plates 23, 23 protruding from the retaining plates 22, 22 of the sandwiching plates 20, 20 by a clasp 27. Hooks 28 and 28 are provided at the distal ends of the string members 26 and 26, respectively. In this embodiment, an example in which a pair of elastic pads is provided on the inner surface of each sandwiching plate is shown, but the number of elastic pads provided here can be arbitrarily selected.

  Next, a method of using the sandwiching apparatus for lifting a plate-shaped building material configured as described above will be described. When the building material 30 is lifted by the plate-shaped building material lifting sandwiching device, first, the building material 30 is disposed between the pair of sandwiching plates 20 and 20. Next, the wire rope 13 wound around a pulley (not shown) previously installed at a high place in the construction site is pulled by a winch (not shown) or by human power. As a result, the sandwiching and lifting member 10 is pulled up as shown by the arrows in FIGS. 1 and 2, and the distance between the upper ends of the horizontal elongate rods 2 of the support arms 1 and 1 is reduced, and each support arm 1. The distance between the sandwiching plates 20 and 20 provided at the lower end of 1 is also reduced. As a result, the building material 30 is firmly sandwiched between the both sandwiching plates 20 and 20, and the building material 30 is lifted in a standing posture. At this time, since the elastic pads 25 and 25 on the inner surfaces of the sandwiching plates 20 and 20 are in close contact with the irregularities on the surface of the building material 30, the building material 30 is lifted without sliding. When the building material 30 is lifted, the building material 30 is engaged with the lower edge portion of the building material 30 where the hooks 28 and 28 of the security string members 26 and 26 are lifted in advance, so that the building material 30 is sandwiched between the sandwiching plates 20 and 20. Even if it slips in between, the fall of the building material 30 can be prevented.

  By the way, in this plate-like building material lifting clamping device, since the sandwiching lifting member 10 is engaged between the upper ends of the horizontal eaves 2 of both the supporting arms 1, 1, the gravity of the lifted building material 30 is increased. Is applied to the clamping lifting member 10 and tensions the clamping lifting member 10, and a force is applied to narrow the interval between the upper ends of the horizontal eaves 2 of both the supporting arms 1 and 1. For this reason, as the building material 30 is heavier, the both sandwiching plates 20 and 20 can sandwich the building material 30 with a stronger force and lift the building material 30 without dropping off. In addition, the sandwiching plates 20 and 20 have a certain area and sandwich the building material 30 via the elastic pads 25 and 25, so that the sandwiching force is not concentrated on one point, and the building material 30 is held with a strong force. There is no risk of scratching the surface even if it is pinched. In addition, even if the surface of the building material 30 is uneven, the elastic pads 25 and 25 are in close contact with the unevenness and exert a large frictional force, so that the building material 30 may slide down while being lifted. Avoided as much as possible.

  In this way, by pulling up the sandwich lifting member 10, the building material 30 is always lifted in an upright position, so that a large area is not required as in the case of lifting in a horizontal state, and smooth even in a narrow construction site. It can be lifted or moved to a high place, reducing the labor of the operator and ensuring safety.

  When the building material 30 is lowered to a required construction site such as a high place, as shown by the arrows in FIG. 3, if the open lifting member 15 is lifted by hand, both the support members are supported by the open lifting member 15. Since the vicinity of the boundary between the horizontally long rod 2 and the support rod 3 of the arms 1 and 1 is lifted, the gap between the sandwiching plates 20 and 20 is opened, and the building material 30 can be easily taken out from the plate-like building material lifting sandwiching device. .

  As described above, the plate-shaped building material lifting clamping apparatus according to the present invention can widen the gap between the sandwiching plates 20 and 20 simply by the operator pulling up the open lifting member 15. The building material 30 can be taken out easily. In addition, the building material 30 can be easily set when another building material is newly sandwiched.

  In the above-described embodiment, an example in which the upper end portions of the horizontal eaves 2 of both the supporting arms 1 and 1 are connected by the flexible string-like sandwiching and lifting member 10 is shown, but as shown in FIG. The pair of links 41 and 41 are connected to the upper ends of the horizontal eaves 2 of both the support arms 1 and 1 via the support shafts 40 and 40, and the wire rope 13 is fixed to the support shaft 42 that connects both the links 41 and 41. Then, the wire rope 13 may be pulled up. That is, even if the upper ends of the horizontal eaves 2 of both the supporting arms 1 and 1 are connected by the pair of links 41 and 41, the upper ends of the both supporting arms 1 and 1 are narrowed when lifted, The building material 30 can be firmly sandwiched by 20 and 20. In addition, the open lifting member 15 shown in the above embodiment can be composed of a flexible member such as a link or a chain in addition to a flexible string. The other configuration shown in FIG. 4 is the same as that of the above embodiment, and therefore, the same reference numerals as those in FIG.

  FIG. 5 shows an embodiment in which a pair of open lever members 50, 50 are mounted instead of the open lifting member 15. That is, in this embodiment, a pair of open lever members 50, 50 which are the horizontally long rods 2, 2 of the both supporting arms 1, 1 and protrude upward from the side portion of the shaft hole on the support rod 3 side. Is provided. Specifically, long nuts 52 and 52 are welded to the side outer surfaces of the side holes of the horizontally long rods 2 and 2 on the side of the support rod 3, and rod-like levers 51 and 51 are screwed onto the long nuts 52 and 52, respectively. Match. According to this embodiment, when the building material 30 is taken out from the plate-shaped building material lifting and clamping device, if the release lever members 50 and 50 are pressed inward, the interval between the clamping plates 20 and 20 is increased. It will be widened and the work can be done very easily. The other configuration shown in FIG. 5 is the same as that of the above-described two embodiments, so that the description thereof is omitted by attaching the same reference numerals. Incidentally, the release lever member in this embodiment has been shown as an example formed by a long nut and a rod-shaped lever, but of course it is not limited to this. The object of the invention can be achieved.

  In the above-described embodiment, as an example of the support rod 3 that hangs down from the horizontally long rod, the support rod that is bifurcated from the horizontally elongated rod has been described as an example, but it is not always necessary to have such a shape. It is also possible to form the support rod so as to hang down from the base end side of the horizontally long rod as it is.
